COUNTING MECHANISM.

Specification of Letters Eatent.

Patented May 5, 1914.

Application filed February 18, 1913. Serial ITO 749,202.

citizen of the United States, residing at Ardmore, in the county ofMontgomery, State of Pennsylvania, have invented certain new and usefulImprovements in Counting Mechanism, of which the following is adescription; reference being had to the accompanying drawings, forming apart or carrying mechanism,

.in side and vertical mesh with. bevel gear hereof.

My invention relates to registering mechanism particularly adapted forregistering the deposition of coins-or like articles and my inventionhas for its object to provide a device for this purpose which will beinexpensive to construct, efiicient and accurate in operation and may beeasily and quickly reset to zero.

With these and other objects hereinafter described in view, myinventionconsists in the construction and combination of elementshereinafter described and particularly pointed out in the claims.

Referring to th drawings: Figure 1 is a longitudinal sectional view ofthe complete counting mechanism embodying my invention. Fig. 2 is across sectional view on line aa of Fig. 1. Fig. 3 is a cross sectionalview on line. bb of Fig. 1. Fig. 4 is a cross sectional view on line c0of Fig. 1. Fig. 5 is a cross sectional view on line (i-d of Fig. 1. Fig.6 shows in front and side view one of the number carrying rings. Fig. 7is a longitudinal sectional view of the counting mechanism without theactuating the parts being in position for operation. Fig. 8 is a viewsimilar to Fig. 7 but showing the parts in position for resetting tozero. .Fig. 9 shows section one of the ring gears by which the numbercarrying rings are operated, Fig. 10 showsin end and side view one ofthe sleeves; and Fig. 11 is a cross sectional view of shaft 16 on liness' of Fig. 8.

In the drawings 1 and 2 indicate respectively the front and rear halvesof a casing in which the counting mechanism is inclosed, these halvesbeing held together by bolts 22. In the lower part of the casing isjournaled a shaft 15 provided with a bevel gear 14 carried by a sleeve12 which is secured to the shaft by pin 30. The bevel gear 1 1 s in 24on shaft 25 on which is secured sleeve 26, the outer end of whichreceives the end of shaft 27 which is the operating shaft and carriesthe usual star wheel (not shown In order that the shaft 27 may be inproper relative position with reference to the counting mechanism it isflattened on one side as shown in Fig. 5

' and the sleeve is provided with a pin 28. 1 In the upper portion ofthe casing is journalecl a shaft 16 which is arranged to be capable of aslight longitudinal movement as well as its movement of rotation.Mounted to rotate freely on the shaft 16 are a series of sleeves 8 shownin detail in Fig. 10. having one face fiat as shown at the right in Fig.10 and hollowed out on the other side so as to form a chamber 8. On itsperiphery each sleeve is provided with a single tooth 9 extending to theright beyond the flat face of the sleeve and each sleeve is alsoprovided on its flat side with a pin 18 at such distance from the centerof the sleeve that when the sleeves are assembled it will extend partway into the chamber 8 of the next adjacent sleeve to the right.

The shaft 16 is provided with a series of pins 17, one for each sleeve 8adapted when the shaft is moved longitudinally to the left to eachengage a pin 18, as shown in Fig. 8. When the shaft is in normalposition as shown in Fig. 7 the pins 17 each lie within the chamber 8 ofa sleeve 8 out of engagement with the pins 18.,

Each of the sleeves 8 carries a numeral ring 5, shown in detail in Fig.6, having numerals marked on its periphery and having secured to itsleft hand face a ring 7 of less diameter than the numeral ring 5. Thenumeral ring 5 is notched on its inner periphery as shown at 32 toreceive the periphery tooth 9 of the sleeve 8 on which it is carriedso'that the numeral ring and sleeve will rotate together. The outerperiphery of the ring 7 is notched at 7 and into this notch extends apin 33 carried by the numeral ring 5.

Mounted to rotate on each of the sleeves 5 is a ring gear 6, shownin'detail in Fig. 9 having inner and outer teeth, the inner teeth beingso formed as to leave between them spaces 29 adapted to receive theperipheral tooth 9, these spaces being ten in number. There is one ofthese ring gears 6 for each numeral ring 5 arranged to lie against itsright hand face between'it and the ring 7 of the next adjacent numeralring.

When the parts arein position to be operated asshown in Fig. 7, thetooth 9' of each parts are in posit-ion to permit the numeralrings to bereset to zero the sleeves 8 are pushed to the left a sufiicient distanceto withdraw the tooth 9 from the notch 29 of the ring gear 6 so as topermit the numeral rings to be rotated independently of the gears 6. v

To the right hand one of the ring gears 6, as shown in Figs. 1, 7 and 8,which is the ring gear for actuating the units numeral ring, is secureda ratchet wheel 3 having peripheral teeth adapted to be engaged bydouble spring detent pawl 19 which is mounted on the end of shaft 15.The teeth of this ratchet wheel and the ends of the.

double pawl. are so formed that the ratchet wheel may rotate in eitherdirection. The

detent pawl aids in preventing either overthrowing or underthrowing ofthe units numeral ring; This ratchet wheel is provided with a hub 3which is cutaway on the end toward the sleeves 8 so as to permit thetooth 9 of the sleeve 8 which carries the units numeral ring to rotatein it, and is also hollowed out at its center on the end toward thesleeves 8 as shown at .3 to permit a pin 17 to rotate in it. Theopposite end of hub 3 bears against the end plate of the casing. In thisend of the hub is formed a circular recess 3 in which is located aspring 4: which bears against the shaft 16 to retain it in either of twopositions into which it may be shifted. To enable the spring to do thisthe shaft is provided with an annular groove 35 and with oppositelyarranged grooves 36, When the shaft 16 is in the. position in which itis shown in Fig. 7 the spring 4: is in engagement with the annulargroove 35 and serves to retain the shaft against accidental shifting ineither direction while permitting'it to be rotated. When the shaft is inthe position in which it is shown in F ig.

8 the spring is in engagement with the notches 36. These notches are solocated that when the'shaft has been rotated asufiicient distance toreset the numeral rings to zero the spring will enter the grooves thusserving to indicate when to stop. the rotation of the shaft in theprocess of resetting. For

the purpose of easily moving the shaft 16 it is provided on its-outerend with a knob or ring. a

hand hold 21.

Secured to sleeve 13 on the shaft 15 is a gear 10 which meshesfwith thering gear 6 which is connected with the units numera Mounted on sleeve12 on shaft 15 are gears 10 and Geneva stop wheels 11, each gear beingin mesh with one of the gears 6 on shaft 16 and each Geneva stop wheelbeing adapted to have the concave faces of its teeth bear against theperiphery of ring 7 and to have the notches between its teeth engaged bypin 33.v The Geneva stop wheel 11 which bears against the ring 7 of theunits numeral ring is secured to the gear 10 which is in mesh with thering gear 6 which is connected to the tens numeral ring,-and so on theGeneva stop wheel against which the ring 7 of a numeral ring of lowerdenomination being secured to the gear 10 which is in mesh with the gear6 of the numeral ring neXt higher in denomination.

In operation when the shaft 27 is rotated it rotates shaft 525 andthrough bevel gears 24 and 14: and sleeve 12 rotates shaft 15. Thisthrough sleeve 13 and gear 10 rotates the gear 6 of the units numeralring and as this is locked to the numeral ring by the tooth 9 of theleft hand one of the sleeves 8, this will cause the rotation of theunits numeral ring. As this completes a rotation its pin 33 engages witha notch 0f the Geneva stop wheel which is at the left of the numeralring and turns it. This causes the gear 10v which is secured to theGeneva stop wheel to rotate and as this is in mesh with the ring gear 6of the tens numeral ring the latter will be rotated one space. Therotation of the tens numeral ring through a complete rotation effectsthe rotation of the hundreds numeral ring, and soon. When it is desiredto reset the numeral rings to zero the shaft 16 is pushed inward intothe position in which it is shown in Fig. 8. This brings the pins 17into position to engage the pins 18 and also pushes the sleeves 8 tothe. left a sufficient distance to withdraw their teeth 9 fromengagement with gears 6. By then rotating the shaft16 the pins 17 will,through their engagement with the pins 18, cause the sleeves 8 to rotatewhich in turn will cause the numeral rings to ronot desire to be limitedto the precise con-' struction and arrangements shown as it is obviousthat many changes in details of construction and arrangement may be madewithout departing from the spirit of my in- 'vention.

Having thusdescribed my invention what I claim is:

1. In a counting mechanism the combinetion of a shaft arranged to rotateand to be longitudinally movable, a series of sleeves carried by theshaft and detachably connected therewith, a series of numeral ringscarrled by the sleeves, a series of ring gears also numeral ring carriedby t carried by the sleeves, means for rotating the gears and meanscarried by the sleeves for detachably connecting the numeral rings and,
